Recording and Identifying Flight Calls of Nocturnal Migrants (for the Fun of it!)

Andy Martin will speak about his experiences in the new field of recording the nocturnal flight calls of migrating birds. Most small birds migrate at night to avoid predators, and they vocalize distinctive chips to stay in touch with each other in the dark.  These calls can be recorded surprisingly well with modest equipment and the birds identified from the recording. Andy will play examples of these recordings and describe the equipment and techniques used.

Welcome to the home page of the Prince George's Audubon Society (PGAS), a local chapter of the National Audubon Society serving Audubon members in the northern part of Prince George's County, Maryland.  PGAS was established in 1972 as a non-profit organization with officers and a board of directors, all volunteers, elected by the general membership.  Membership in PGAS is obtained through the National Audubon Society.  PGAS members receive our chaper newsletter, The Bluebird, and are encouraged to actively participate in chapter activities including a monthly speaker series, field trips, annual bird counts, and other special events. 

This website is for members of PGAS to keep up to date on program and field trip schedules and other chapter activities.  In addition, this website serves as a resource for non-members to find out more about Audubon and PGAS and to explore the benefits of membership.  Non-members are welcome to participate in our meetings and field trips and are free to take advantage of the local birding and environmental information on this website as well as the links to a wide range of related information available on the internet.  Of course, if you live in northern Prince George's County we would love to have you as a PGAS member, and membership information is always available.
